Up to 1984 on the Network DVDs now- there's one episode that's not very good quality. Looks like a VHS/Beta/U-matic copy that's been zoomed into to cut off a timecode or something. Did they lose the master tape? Seems strange that when they were able to keep all the episodes from the 60s and 70s when so much is lost from that era, that an episode from 1984 seems to have gone walkies. Though as we're losing a 1985 episode of Top Of The Pops on BBC4 this week for what looks like the same reason, it clearly did happen.
